Writer, painter, sculptor and composer
Brion Gysin (Britain, 1916) was the true inventor of the "cut-up" technique
made popular by his friend William Burroughs. The two experimented with it
while in Paris during the 1950s,
Burroughs focusing on novels while Gyson applied it to just about any art,
including "music" (audio cut-up).

I Am That I Am (1960) is a trancey recitation, a premonition of both
minimalism and spoken-word performance.

He also invented a "Dreamachine" (1961), a spinning cylinder that emanates
light to be experienced with the eyes closed.
